The Lowdown
Alright, surfers, Rusty here, stoked to talk waves for Costeño Beach. Right off the bat, the water’s sitting at a warm 82°, which is about average for this time of year, so trunks are the way to go.
Alright, let's be real. The next week and a bit is looking pretty flat and messy. We've got a lot of NE windswell, but it's mostly weak and coming in with a cross-onshore breeze that’s just chopping things up. The energy is all over the shop, with readings like 958 and 717 early on, which sounds like a lot but it’s just wind swell, not real groundswell. The period is short, mostly 8-9 seconds, and that combo is just not going to give you anything clean or powerful.
The first real window where things start to look up is the morning of Friday, August 21st. The wind drops out to a glassy calm, and we get a little 6ft pulse from the NE with a combined energy of 364. It’s not huge, but it’ll be the cleanest surf we’ve seen for a while. The afternoon stays glassy too, but the swell eases off a touch. Still, that Friday is your pick for the first week.
After that, it goes back into the doldrums for a few days with more cross-onshore junk. It’s not until the morning of Thursday, August 27th that things get really interesting. The wind is light and glassy, and the swell picks up to 5ft, but the period jumps to 9 seconds and the energy reading jumps up to 516. That’s a proper swell pulse, not just local wind slop. It’s a northeast swell, which is right in the pocket for this break. That Thursday morning is the standout. It’s going to have some shape and push to it, and with the glassy conditions, it’ll be fun.
Remember, this is a beach break and a long-period swell can sometimes make them close out, but at that size it should be fine. This is the one to circle on the calendar.
The weekend after that looks like it drops back into the average, around 4ft to 5ft, but with the wind coming back onshore, so it will be a bit bumpy again. Still, there's a couple of glassy windows on the Sunday afternoon of the 30th, so you might get a sneaky one in.
All in all, it’s a slow start, but there are a couple of windows. The call is Friday the 21st for the cleanest, but Thursday the 27th for the best size and shape. Don't sleep on it when the glass comes up.
Rusty, out.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
